Required Methods

fn as_raw_PCTSignaturesSQFD(&self) -> *const c_void

Provided Methods

fn compute_quadratic_form_distance(
    &self,
    _signature0: &dyn ToInputArray,
    _signature1: &dyn ToInputArray
) -> Result<f32>

Computes Signature Quadratic Form Distance of two signatures.

Parameters

• _signature0: The first signature.
• _signature1: The second signature.

fn compute_quadratic_form_distances(
    &self,
    source_signature: &Mat,
    image_signatures: &Vector<Mat>,
    distances: &mut Vector<f32>
) -> Result<()>

Computes Signature Quadratic Form Distance between the reference signature and each of the other image signatures.

Parameters

• sourceSignature: The signature to measure distance of other signatures from.
• imageSignatures: Vector of signatures to measure distance from the source signature.
• distances: Output vector of measured distances.
